Description

Represents the raw exponent part in the fraction number.

Exp is represented on 11 bits.

The Exp property provides direct access to the UInt64 exponent part of the floating-point value.

The number 21, represented in binary, is 10101. After the normalization, the number looks like this: 1.0101 * 2^4. To calculate the Exp, the bias, 1023, is added to 4, the exponent after the normalization.
